Context hook information specified in the
<resourceid> element in
the DITA map or in a DITA topic enables processors to generate the header, map, alias and other
types of support files that are required to integrate the user assistance with the application.
Some user assistance topics might need to be displayed in a specific window or viewport, and
this windowing metadata can be defined in the DITA map within the
Context hook and windowing information is ignored if the processor does not support this metadata.
User interfaces for software application often are linked to user assistance (such as help systems and tool tips) through context hooks. Context hooks are identifiers that associate a part of the user interface with the location of a help topic. Context hooks can be direct links to URIs, but more often they are indirect links (numeric context identifiers and context strings) that can processed into external resource files. These external resource and mapping files are then used directly by context-sensitive help systems and other downstream applications.
Context hooks can define either one-to-one or one-to-many relationships between user interface controls and target help content.
The metadata that is available in
<ux-window> provides flexibility for content developers:
<prolog>elements, or both. Context-dependent metadata might be best be kept with maps, while persistent, context-independent metadata might best stay with topics in
Context hook information is defined within DITA topics and DITA maps through attributes of
In some help systems, a topic might need to be displayed in a specifically sized or featured
window. For example, a help topic might need to be displayed immediately adjacent to the user
interface control that it supports in a window of a specific size that always remains on top,
regardless of the focus within the operating system. Windowing metadata can be defined in the
